SPECIFICATION forming part of Letters Patent No. 277,390,.dated May 8,1883.

Application filed August 16, 1882.

(No model.)

To all whom it may concern:

Be it known that I, J OSEPH Wars, a citizen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented new and useful Improvements in Circuit-Instrumentsfor Electric Railroad-Signals, of which the followingis a specification.

The object of this invention is to' ring two or more bells at two ormore different streetcrossings, by the action of one and the samebattery, for such a length of time as may be desirable. The peculiarconstruction of the devices which I use for that purpose is pointed outin the following specification.

In the accompanying drawings, Figure 1 represents alongitudinal verticalsection in the plane w m, Fig. 2. Fig.2 is a plan or top view.

Fig. 3 is a transverse vertical section in the plane 3 y,.Fig. 1. Fig. 4is a diagram showing the connections.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a base, of wood or other badconductor of electricity. On this base are secured two pairs ofelectro-magnets, B B, O O. The armature D of the elect-ro-magnets B B issecured to a vertical lever, E, which has its fulcrum on arockshaft, a,and is retracted by a spring, I). On the face of this armature-lever issecured a contact-spring, c, and when the armature D is attracted thisspring comes in metallic contact with a screw, d. The armature F of theelectro-magnets G is secured to a horizontal lever, Gr, which has itsfulcrum on a rock-shaft, e, and is retracted bya spring, f. On its faceis secured a contact-spring, g, and when the armature F is attractedthis spring comes in metallic contact with a screw,h. On the back of thearmature-lever E is secured a block, t, and if the armature D isattracted the end of the armature-leverG of the electro-magnet 0 dropsbehind this block, (see Fig. 1,) and the metallic contact between thespring 0 and screw dis maintained, even when the circuit through theelectro-magnet'B is broken, until the electromagnets O are vitalized andthe armatureFis attracted. As soon as the rear end of the armature-leverG rises the armature-lever E'drops back and the block catches beneaththe lever G, so as to maintain the metallic contact between the spring 9and the screw h. On the l armature-lever E are secured additionalcontact-sprin gs, insulated from each other, to close additionalcircuits through additional setscrews. In the drawings I have shown oneadditional contact-spring, j, and a corresponding contact-screw, It.

larger number of such screws and springs are used they must all beinsulated one from the other.

In applying my instrument'for operating alarm-bells on street-crossingsthe connections are made as shown in Fig. 4. In this figure the letter Rdesignates a railroad, and S Sare street-crossings, close to which areplaced the bells O O. T T are two track-instruments, one for closing andthe other for reversing the circuit. These track-instruments areactuated or acted on by the wheels of a passing train, and they mayconsist of insulated track-sections, or of levers, or any othermechanism suitable for the purpose. Q is the battery,which, togetherwith my circuit-instrument, is placed in a suitable house. One pole ofthe battery is grounded, and the other pole connects. by a wire, 10,with one end of the helix of electro: magnets B. The other end of thishelix connects by a wire, 11,with one end of the track-instrument, andthe other end of thistrack-instrument connects by a wire, 12, with theground. If a train passes in the direction of arrow -1, the two ends ofthe track-instrument T are brought in metallic contact by the wheels ofthe passing train, the circuit through electromagnet B is closed, andthe armature D is attact with the screws d 7:, respectively, andrearmature-lever G on the block 2'. By the contact of the springc andscrew (1 the circuit the battery, through wires 10 and 13, to screw d,through this screw to spring 0, armature E,

is mounted, thence through wire let to the bell mechanism, and wire 15to the ground. The

This contact-screw is insulated from the contact-screw (I, and it atained in that position by the action of the through the hell 0 isclosed as follows: from and the metallic frame E, in which this levertracted. The springs c j are broughtin-conmagnets O O, and wire 20, tothe track-instrument T, and through this track-instrument and wire 21 tothe ground. By this circuit the electro-magnets O O are vitalized, thearmature F is attracted, the armature-lever G releases the block 2', andthe armature-lever E drops back, so as to throw the springs 0 out ofcontact with the screws d It and stop' the action of the bells O 0. Itis obvious that instead of bells other visual or audible signals can beused in connection with my circuit-instrument.

' I am aware that circuit-instruments have been made heretofore in whichthe armature lever of one electro-magnet is locked in its closingposition by the armature-lever of another electro-magnet. Such,therefore, I do not claim as my invention.

I do not claim anything shown or described in thepatent of W. Robinson,No. 109,549, dated November 22, 1870. V

\Vh atIclaim as new, and desire to secure by Letters Patent, is-

The combination, with the two electro-magnets B 0, their armature-leversE G, block a, secured to lever E, contact-springs 0 j, andcontact-points d It, insulated from each other, of the single battery Q,bells O O, track-circuit-closing instruments T T, and the specifiedelectrical connections-having said battery as a common terminus, as setforth.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
